WILLIAM I.. scrummm, or o IIIcAGo, ILLINOIS VPLASTER AND PACKAGETHEREFOR Application led October 3, 1928. `Serial Ilo. 810,163. y

My invention relates to adhesive plasters for use in the removal and.preventlon of bunions, callouses, and similar foot and L skindisorders, and has among its objects the provision of an improved. formof plaster and an improved package mounting therefor.

A further object is to provide an improved plaster which willfirmly-adhere to the skin.

A further object is to provide an improved plaster which will not stickto the clothing of the user.

A further object is to provide an improved plaster package in whichthemedicament is protected by the plaster and the plaster may f be removedfrom the package with or without the medicament as des1red.-

Other objects will appear from the following description, 'referenceybeing had to the accompanying drawing, in-,which Fig. 1 is a plan viewofthe crinoline sheet upon which the plasters are mounted;

Fig.` 2 is an end elevation thereof;

Fig. 4 is an enlarged transverse sectional view taken on the line 4-4 ofFig. 3;

Fig. 5 is an enlarged longitudinal sectional view taken on the line 5-5of Fig. 3;

Fig. 7 is a. sectional view thereof taken on the line 7-7 of Fig. 6. v

In the removal of corns, bunions, callouses, etc., it is desirable iirstto apply a medicament by means of a plaster and after the disorder hasvmoval of the hardened skin formation, to apply an unmedicated plasterto protect the part and prevent recurrence of the disorder.

I have provided an improved plaster or ad which may be conveniently usedto accomplish both of these objects and purposes.

Referring to Fig. 1, a. sheet 8 of antiseptic crinoline or othersuitable material of substantially rectangular shape has a plurality oftabs 10 formedintegrally therewith and extending outwardly therefrom,there being four such tabs 10 equally spaced on each side of the sheet 8in the particular embod-iment been alleviated by the softening and re-yshown. Each of the tabs 10 comprises a neck portion 12 of decreasingwidth and a substantially circular head portion 14.

Discs 16Iof medicament are pressed upon each of the head portions 14 ofthe tabs 10. These discs arelpreferably of wax-like consistency andcontain as one of the usual ingredients salicylic acid. .A number ofdifw erent formulae for the preparation of the medicament are well knownin the art and need Anot here be specified. The disc 16 will adherefirmly to the crinoliney head 14 of the tab since it is forced into theinterstices present between the threads thereof, and, in fact, isimpregnated in the fabric. i

.Each of the tabs 10, after the medicament has been attached, is folded.upon the dotted line 18 so as to lie substantially at upon the sheet 8.Plaster pads 20 arev then placed over the tabs to hold them in place,each of the plasters having a facial depreion or recess 22 suiiicientlylarge to receive the head 14 and disc of medicament.

As best shown in Figs.,3, 4 and 5, each of the plaster pads comprises asubstantially elliptically shaped piece 24`of closely woven fabrichaving a coating 26 of a suitable anti-V septic adhesive. A pair ofelliptical ring shaped fabric pieces 28 and 30 in outline substantiallythe same as piece 24, are joined to each other by a layer 32 of adhesiveand to the piece 24 by its adhesive coating 26. The lowermost ring piece30 has an antiseptic adhesive coating 34.

From an inspection of Figs. 4 and 5 of the drawing, it will be observedthat the peripheral edges of the fabric pieces 24, 28 and 30 are bentdownwardly forming curved flanges which cover the edges of the adjacentlayers of the adhesive, thus preventing the adhesive from oozing fromthe edge of theplaster and coming in contact with the hose or otherarticle of clothing of the user. Furthermore,

the plaster, because of this peripheral chamfer, will sticktighter-because parts ofthe clothing or other objects will tend to slideover the plaster rather than abut against and turn up the edge thereof.

Figs. 6 and 7 illustrate aplaster or pad adapted for application tocallouses,'bunions,

vals

. 46 having layers 48 and 50 ofadhesive. Its

- edges are chamfered inthe samemanner and it is adapted to be securedupon a sheet of crinoline or similar fabric over a disc of medicament inthe same way as previouslyvk described with reference to theplasters 20.

Obviously the pads or -plasters and the discs of medicament may be madeof any other shape and size suited to the particular :lliv

use for which they are desired.

- When it is desired to; use the plaster with the medicament, as forinitial application to f a. corn, the plaster pad is peeled from the 26of the adhesive and be retained in the openl ing 22 of the.k plaster.

sheet 8' beginning at the edge opposite the .neck"12, e. g.,point A inFigs. 3 and 4. j As fthe pad is being raised the disc 16 and the head 14ofthe tab 10 will adhere to the layer After ythe pad has been completelypeeled from the main porf 'tion of the sheet-8 it will adhere only tothe medicament and the tab, whereupon the plaster with the medicamentattached Vmay readetc.`

ily be severed from the sheet by tearing or cutting the neck-12, andapplied'to the corn,

After the corn or other disorder has been suiiiciently treated withmedicament it is "usually desirable to cover it with a plaster withoutmedicament'to reduce friction upon the part and also to reduce thepressure thereon by distributing the pressure over a greater area. Forthis purpose I provide a number "of vplasters without medicament,namely,

those in the central longitudinal row (Fig. 3). After this row has been.used 'up the plastersin the two outer rows may be removed from thevsheet withoutthe medicament'by peeling them therefrom beginning withthe edges which overlie the necks 12 of the tabs,

e., g., by startingl at the point B,'Figs. 3 and 4.. When theplaster 20is peeled fromthe sheet 8 in this manner, it will at the same time .-un-

peel fronrthe tab 10 and may thus be rein vsaid vouter plies and adhereto the a septic fabric sheet, a pad comprising a plura ity of plies ofclose y woven clot joined by intermediate layers of an antisepticadthereby permanently secured to said sheet,

the greatest cross-sectional area of ysaid disc being) less than thearea of said opening, said disc eing adapted to fit within said o eningesive on said exposed portion of the adjacent ply.

2. A plaster pad package comprising an antiseptic sheet, a plurality ofplaster pads each having a recessed' adhesive covered face adhering tosaid sheet, and. a plurality of discs of medicament permanently securedto a portion of ,said sheet adjacent said pads, said discs beingsmaller'than therecesses in said pads and being adapted to fit thereinand be detachably secured to the bottom of the recesses in -saldY padsby adhesion of the portions of the sheet adjacent said discs to theadhesivel on the pad.

3. A plaster pad package comprisingvan.

antise t-ic sheet having a plurality of tongues exten ing outwardlytherefrom, pellets of medicament secured to the ends of each of saidtongues, said tongues being folded inwardly over said sheet, and aplurality of plaster pads, each' having a recessed adhesive covered faceadhering to said sheet, the recesses in said pads lying over the ends ofsaid tongues so that said pellets lie within the recesses and adhere tothe plaster pads at the bottoms `of the recesses.

In witness whereof, I hereunto, subscribe my namefthis 1st daly ofOctober, 1928.

The -invention is capable .of widevaria-tion within'equivalent'limitsand I contemplate such variation as may be desirable or useful in theparticular adaptation of the invention shown, or in ,its adaptation forlother purposes. I vdo not restrict myself in any un-l essentialparticulars, but what I claim and desire to secure by Letters Patent is:
